• C. $52$
• D. $70$

Answer 1

Answer: (B)

$54$

We have to find the relation between $72,53$ and this relation will be applied to the Next, and accordingly we have to check the options

(i) $72:53$

Let us check the sum of digits of the numbers.

$72\Rightarrow 7+2=9$

$53\Rightarrow 5+3=8=(7+2)-1$

applying this relation

$64\Rightarrow 6+4=10$

Now for the number related to $64$

sum of digits should come out to be $10-1=9$

Now we have to look at the options

Option $B$ - $54$

$54\Rightarrow 5+4=9$

Answer is $64:54$
